INSTALLATION INSTRUCTIONS - ENGLISH
Before turning water on during either rough-in or
trim-out, ensure that the cartridge retainer clip is
in place. The cartridge and retainer clip were prop-
erly installed and tested prior to
leaving the factory. While unlike-
ly, it is possible that due to han-
dling the retainer clip may not be
properly installed. If the retainer
clip is not properly installed, water
pressure could force the cartridge
out of the casing causing personal
injury and/or water damage.
To Operate Shut-off Stops
This type is integral with casting, actuated
by a screwdriver, requiring a 90° turn to open
or close. When the screwdriver slot is verti
cal the stop is closed; when horizontal the stopis
open.
MAKE SURE ALL WATER
SUPPLIES ARE OFF.
Rough-In
UP
Install the casting with the
arrow pointing up
or the word "TOP" facing the ceiling. If the valve is
used for shower only, plug the bottom outlet. If the
valve is used for both a tub and shower, connect
the top outlet to the shower and the bottom to the
tub spout. Secure all pipes and the shower ell
and/or tub drop ell. Use Teflon tape on all threads.
Caution: This valve is equipped with
the Moen long-life POSI-TEMP cartridge
designed for smooth, trouble free operation.
When soldering do not heat valve any
higher than necessary. Overheating may dam-
age the cartridge or rubber stops. Following
this direction will allow you to solder without
removing the cartridge or rubber stops.
Warning: The cartridge and rubber stops MUST
BE REMOVED before brazing or resistance (elec-
tric) soldering.
Flushing
Important: Before closing wall openings,
pressure test valve and complete system using
flushing instructions.
Pipe chips, sand and other solids found in new and
renovated plumbing can damage the sealing sur-
faces of the cartridge causing leakage or spool
1
blockage. To avoid damage, DO NOT TURN ON
SUPPLY VALVES until instructed.
Make sure both hot and cold supplies are off.
Rotate cartridge stem until the notch flat points up
Clip
to relieve pressure and insure complete shut-off.
Remove the cartridge (see Disassembly). Slowly
turn on both hot and
cold supplies and flush out the body and lines.
Close the hot and cold supplies and replace car-
tridge (see Reassembly). Turn on both
supplies and check the system for leaks.
Cartridge Ears
If the balancing spool becomes stuck, apparent
during the trim-out test, the valve will only deliver
a trickle of water or will only deliver hot or cold
water. If this occurs, proceed as follows:
Make sure that both hot and cold service lines are
ON and ensure that the integral stops are open
(stop models). The valve will not operate unless
both supplies are on.
If the valve still does not function properly,
turn off both hot and cold supplies and remove
cartridge. The inner spool in the cartridge should
shake back and forth freely. If this
does not happen, remove the stem assembly from
the cartridge sleeve, remove the cap from the
assembly and remove the balance spool. Carefully
clean any foreign material from the balance spool
and stem assembly and reassemble. Caution: DO
NOT DAMAGE
O-RINGS. If the spool still does not free up, replace
the entire cartridge.

C.C. SPOUT:
The Moen slip fit spout is designed with an
o-ring seal, specifically for installation with
copper water tube. Lookout must be free of burrs
inside and out. The edge must not be rolled. The
outside surface must be free from nicks and
scratches.
Press and twist the spout onto the lookout upside
down. Tighten clamp screw with a 5/32" hex
wrench until it starts to bind. Correctly position
spout against the wall and tighten by hand. Fur-
ther tightening with pliers or hex wrench is not
needed. Do not overtighten.
I.P.S.
IPS SPOUT:
CAUTION: This spout is ABS plastic and will crack
when in contact with some pipe thread com-
pounds. We recommend using Teflon Tape.
Screw tube spout onto pipe and tighten by hand. If
final turn by wrench is needed, use small wrench
with smooth jaws or pad wrench teeth with rag.
Pull outward to avoid scratching wall. DO NOT
